For more actually simulate the problem of satellite in space, carry out simulation design for 3 freedom air floating platform satellite gesture control system. Use air floating platform to carry out satellite dynamics and dynamics simulation, establish control torque gyroscope 5-pyramid structure scheme, comprehensively consider the gyroscope group structure, design torque gyroscope group control law, and realize air floating platform stability and gesture fast maneuvering control. The simulation results verify the correctness, rationality and efficiency of the scheme, and reduce the unexpected control risk of satellite gesture and provide the reference for other satellites control system projects.
